Never fear, here's what you do.
Cut around the bottom grooves so that you have one piece that looks kinda like a flower.
Punch some holes, or use a hot needle to make holes.
Gather some string, fishing line, dental floss, or those metal craft rings.
String them together and VIOLA! You have an instant wall hanging, doorway curtain, or privacy blinds for your window.
Or you can also make a hole in the middle of them and insert a LED into each of them for some pretty flower lights!
You can also spray paint them to get different effects and colors.
Very fun, useful, and great to set up for kids, especially as doorway hangers.
